Subject: [PATCH v2 2/2] Staging: rts5208: helper function to enable interrupts during reset
Date: Sun, 19 Oct 2014 21:30:03 +0200 [thread overview]
Message-ID: <1413747003-13655-3-git-send-email-fabio.falzoi84@gmail.com> (raw)
In-Reply-To: <1413747003-13655-1-git-send-email-fabio.falzoi84@gmail.com>
Define the helper function rtsx_enable_pcie_intr to shorten the
rtsx_reset_chip code and get rid of the LONG_LINE checkpatch warnings.
